The field experiments were carried out in the Institute of forage crops - Pleven during the period of 2009 - 2012. Studied was the variation of some genotypes of forage peas belonging to different subspecies with the directions of using methods of pick out, sexual hybridization and mutagenesis. Applied was crossing between varieties with alternative traits. It was found that in F2 generation there was great diversity of types and created opportunity for selection of suitable progenies. Perspective lines steady on stress factors were selected. The inheritance of the element of productivity is d...
The field experiments were carried out in the Institute of forage crops - Pleven during the period of 2009 - 2012. Studied was the variation of some genotypes of forage peas belonging to different subspecies with the directions of using methods of pick out, sexual hybridization and mutagenesis. Applied was crossing between varieties with alternative traits. It was found that in F2 generation there was great diversity of types and created opportunity for selection of suitable progenies. Perspective lines steady on stress factors were selected. The inheritance of the element of productivity is determined mainly by additive dominant gene effects. The phenotypic diversity of the quantitative traits in F2 is characterized with continual variability and transgression activities. The uses of method on experimental mutagenesis is analyzed the reaction of four forage peas genotypes to radiation influence (gamma rays Cs137). For actively influence on the mutability and the heritability of the organisms should be matched with suitable methods and ways for change of the ancestral information.
